MACHINE FOR POWDERING SHEET METAL, 800.

SPECIFICATION forming part of Letters Patent No. 465,815, dated December 22, 1891.

Application filed August 18, 1891. Serial No. 402,554. (No model.)

To all whom it may concern:

Be it known that I, I-IUBERT CLAUS, a resi dent-of 'lhale in-theJIarz, Empire of Germany, have invented an Improved Machine for Powdering Sheet Metal and otherSubstances,

' after more fully described.

In the drawings, Figure 1 represents a vertical longitudinal section on the line 1 1, Fig. 2, of my improved powdering-machine. Fig. 2 is a plan or top View, partly in section, of said machine, the line 2 2, Fig. 1, indicating the plane of section.

The letter A in the drawings represents the main frame of. the machine. In the lower part of this frame are the bearings for two parallel shafts B and 0, each carrying a pair of sproclcetuvheels a and b, over which sprock' et-wheels endless chains (Z d are placed. These endless chains are indicated in Fig. 2 by double dotted lines and in Fig. 1 bysingle heavy dotted lines. The two endless chains cl cl are connected by slats e, made of wood or analogous substance and riveted or otherwise tied to the chains, and over these slats is placed an endless band, of wire-gauze f or of analogous fabric. All these parts are arranged to constitute an endless carrier for the plates or articles to be powdered, said carrier being put in motion whenever rotary motion is imparted by a belt 9 (see Fig. 1) to a pulley on the shaft 0 from a suitable driving-pulley 71.

Suitable idle-wheels 'i are hung to the frame A at proper intervals to support the chains (Z (Z and the fabric apron f in a substantially horizontal position during their passage from one sprocket-wheel to the other. A suitable brush j is placed beneath the apron f to remove from its surface any powder which may adhere thereto. Above this endless apron the frame A extends and carries at its upper end a hopper D, the lower end of which is closed by converging flaps k, which can be moved close together or more or less apart by suitable screws and nuts Z or by other means. Below this hopper D is a shaft E, which is driven by a belt m or by other means from one of the driving-wheels, and which carries a series of brushes a at, said brushes being arranged, by preference, in the convolute manner which is represented in Fig. 2 of the drawings. ielow the shaft E is a serni-cylindrical sieve F, which is supported on the framing A in such manner that it may be shaken by the agitator G, said agitator being a ratchet-like wheel actuating against a lug on a bracket -0, that projects from the sieve The hopper-body D is connected with a downwardly-extending chamber II, which reaches down as far as the sieve F, and this hopper-body and its chamber II are also provided with projecting brackets pp, which can be actuated by agitators I I, that are rotated by connections with the driving shafts. \Vithin the hopper I), I prefer to place a stirring-wheel J, having projecting blades, the shaft of said stirring-wheel receiving rotary motion by a belt connection from the shaft E, said belt connection being indicated by dotted lines in Fig. 1. It is quite evident that instead of the belt connections herein mentioned, and indicated in the drawings, other means for imparting rotary motion to the wheels and agitators and shafts may be substituted without departing from the spirit of my invention.

Eelow the sieve F and below the upper layer of the endless apron fare stationary hopper-like vessels L and M, which are intended to conduct any powder that does not reach the substances to be covered to a receptacle placed beneath the apron.

This being, in general, the construction of my machine, its operation is as follows: The powder-enamel or other powder to be spread upon theplates or articles carried by the apron fis first placed into the hopper D. The iron plates or articles to be powdered are then deposited upon the apron f. The machine being then set in operation, by revolving the main driving-shaft N the apron f is moved in the direction of the arrow shown in Fig. 1, carrying the metal plates or things to be powdered along in the same direction underneath the sieve F. By means of the screw or screws Z the flaps 7c are then spread to the desired extent, so that the powder from within the hopper D is discharged into the sieve F, through the meshes of which it is forced by the rotating brushes n, so that it will be deposited in substantially even layers upon the plates or articles carried by the apron. Any coarse admixtures of the powder that are unable to pass through the meshes of the sieve may at proper intervals be removed from the sieve through an opening r in the side wall thereof, which opening during the operation is closed by a suitable door or slide. During the action of the machine the sieve is shaken by the agitator, and also the hopper, to insure the proper discharge of the powder therefrom, and to also impart to the brushes at varying places a firmer grip upon the walls of the sieve. Any powder which is not de- "posited upon the plates or articles carried by the apron f will pass through the stationary guide-hoppers L M into a receptacle placed beneath them or into a heap on the floor. Suitable means for promptly stopping the machine may be devised, also for quickly setting it in motion.

hat I claim is 1. In a machine for powdering plates, fabrics, and the like, the combination of an upper hopper D, and means, substantially as described, for agitating the same, with the receiving-sieve F, and means, substantially as described, for agitating the same, brushes '12, within said sieve, and means, substantially as described, for revolving said brushes, and with a lower endless apron f beneath said sieve and adapted to receive powder directly from said sieve, and means, substantially as described, for moving said apron, all arranged for operation substantially as herein shown and described.

2. The combination of the hopper D and its adjustable flaps K K, with the sieve F, brushes n, mechanism, substantially as described, for revolving said brushes, and mechanism, substantially as described, for agitating said sieve F, and with the endless apron f, all arranged for operation substantially as herein shown and described.

The hopper D, and means, substantially as described, for agitating it laterally, 'com bined with the adjustable flaps K at its outlet, and means, substantially as described, for supporting said flaps in stationary support and for setting the flaps at varying 'distances apart, substantially as herein shown and described.

IIUBE'RT CLAUS.
